Problems solved by technology

This technology can use all light from visible light to near-infrared for curing operations, which is safe and has a short curing time. It effectively solves the problems caused by peroxide curing, but it does not fundamentally solve the surface layer that is in contact with the air during curing. Part of the problem of insufficient curing

application example 1

[0097] To 100 parts of vinyl ester resin [VE-1], add 1.5 parts of a diacylphosphine oxide compound photoinitiator that is photosensitive to all light in the wavelength range from ultraviolet light to visible light: two (2, 4, 6- Trimethylbenzoyl)-phenylphosphine oxide (trade name: Irgacure  819, produced by Ciba Seika Co., Ltd., hereinafter referred to as I-819), obtained a photocurable resin composition-1 capable of photosensitivity to all light in the wavelength range from ultraviolet light to visible light. The composition contains Hydroxyl amine compounds.

[0098] Then pour the photocurable resin composition into a frame made of glass plate to a thickness of 3 mm, and then use a 2KW metal halide lamp [trade name: Dynabeam2, manufactured by Toshiba Lighting Technology Co., Ltd.], which is a visible light source. Irradiate it at a distance of 1m for ten minutes to fully cure it. The bending strength and Barcol hardness (BH) of the obtained molded panels were measured. T...

comparative example 1

[0100] A room temperature curing catalyst butanone peroxide / cobalt naphthenate (Co: 6%)=1.0 part / 0.5 part was added to 100 parts of vinyl ester resin [VE-1] to obtain room temperature curable resin composition-1.

[0101] Then, the room temperature curable resin composition-1 was poured into a frame made of glass plate so that the thickness reached 3 mm, and it was left at room temperature for 24 hours to be cured at room temperature. Then prepare a molded plate that has undergone secondary post-curing for two hours at 120° C., and measure the flexural strength and Barcol hardness (BH) of the molded plate. The results are shown in Table 1. It can be seen from Table 1 that when the room temperature curable resin composition-1 is cured at room temperature, the same hardness as room temperature curing + secondary post-curing cannot be obtained even after curing for 24 hours. Resin composition-1 can obtain hardness and physical properties equivalent to room temperature curing + s...

application example 2

[0104] To 100 parts of unsaturated polyester resin UP-1, add 3.0 parts of 2,4,6-trimethylbenzoyl diphenylphosphine oxide (trade name: Darocur  TPO, produced by Ciba Seika Co., Ltd.) and 0.3 parts of copper naphthenate to obtain a photocurable resin composition-2 with metal salts and photosensitive to all light in the wavelength range from ultraviolet to visible light.

[0105] Add 1.5 parts of I-819, 0.5 parts of cobalt naphthenate, and 1.2 parts of butanone peroxide to 100 parts of polyester methacrylate resin UPM-1 to obtain resin composition-3 with room temperature curing function and light curing function.

[0106] Then use photocurable resin compositions -2 and -3, according to the surface mat +450g / cm 2 The laminated product structure of 3 layers of chopped strand mat + surface mat, so that the glass fiber content reaches 25wt%, and then a visible light source 250W metal halide lamp [manufactured by Mitsubishi Electric Corporation] is irradiated for 15 minutes from a di...

Abstract

Composition of the visible light solidified resin includes following portions in wt%: (1) 100 portions of collective compound containing at least one unsaturation group in olefin class (such as unsaturated polyester, vinyl ester etc.); (2) 10-100 portions of at least one monomer containing unsaturation group in olefin class; (3) adding 0.05-5 portions of photoinitiator in free radical type to 100 portions of resin; (4) adding 0.1- 1000ppm portions of metal salt to 100 portions of resin; (5) adding 0.1- 10 portions of amine compound to 100 portions of resin. Using visible light solidifies the resin. Other reinforcing material can be added to meet different methods to produce products of glass fiber reinforced plastic. Solving issues of solidified peroxide and not good operability, the invention also solves issue, which is not solved by other visible light solidifying methods, of not enough solidifying surface layer contacted to air.
